Why we made this free

We built RetentionLab because Shopify brands between $500K and $5M were getting ignored by the agencies that only want enterprise accounts, and overcharged by freelancers who disappear after setup.

The honest truth about email marketing is that most of it isn't complicated. Welcome series, abandoned cart, post-purchase — there's a right way to build each one, and it's knowable. It's just rarely taught clearly.

So we wrote it down. Seven lessons, the way we'd explain it to a founder over coffee. If you read them and decide you want us to build it for you, we'd love that conversation. If you read them and build it yourself — great. That's the point.

— Erin, RetentionLab
